Abstract
Systems and methods for uniquely identifying areas within a facility for location services. The methods involve: operating a plurality of beacons disposed within the facility; emitting, from a first beacon of the plurality of beacons, a first beam having a first beamwidth in a manner so as to communicate at least a unique identification code associated with a first physical area of the facility; changing a value for a beamwidth parameter to modify an area of coverage for the first beacon; and emitting, from the first beacon, a second beam having a second beamwidth in a manner so as to communicate at least the unique identification code associated with the first area of the facility, where the second beamwidth is different from the first beamwidth. The changing is performed autonomously by the first beacon or in response to the first beacon's reception of a command from a remote beacon receiver.
